MILL-POND WASTE-WATER GATE.

SPECIFICATION forming part of Letters Patent No. 398,842, dated March 5, 1889.

Application filed June 5, 1888. Serial No, 276,162. (No model.)

T 0 all who/7t it mn concern:

Be it known that l, \YILLIAH TIPTON MC- CLosKEY, a citizen oi the United States, resid- 1 ing at \Vestport, in the county of Clinton and State of Pennsylvania, have invented certain new and useful. Improvements in Mill-Pond \Vaste-Il'ater Gates; and I do declare the following to be a full, clear, and exact descrip- I tion of the invention, such as will enable oth- Q ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to make a waste-water gate for mill-ponds in order to keep the head of water at the same elevation whether the mill is running or standing still; also to adjust itself automatically in freshets, so as to discharge all surplus water.

Figure l of drawings is an elevation in perspective,showing the basin or pond separated from the chute leading to the mill drive-wheel Fig. 2 is 1 ends. The weights E are arranged on the bars a in such a position and at such leverage as tohold the breast 0 against the stops F F. As soon as the head of water beginsto increase beyond that to which the gate has been set the increased pressure upon the breast C causes thelatter to augment its opening, For instance, I first move the weights to raise or lower the head of water toward or from the beam A, adjusting so as to raise the water in the pond two feet. New, according to my observation, one inch rise of water will cause the gate to open, turning, of course, in the arc of a circle having the beam A as its center. As the rise of water and consequent increase of pressure on the breastC continue the gate will open more and more, so as to dis- .charge the superfluous volume of water.

Having thus described all that is necessary to a full understanding ofmy invent-ion,wl1at I claim as new, and desire to protect by Letters Patent, is

A mill-pond waste-water gate consisting of the beam A, pivoted in posts B B, the breast 0, connected by arms a with said beam, and

the bars a, attached to said beam, said bars being provided with movable weights on their free ends, as and for the purpose set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
